Subject: Asymmetry in Genius?

Author: Vladimir Medvedev

In the thread about chess programmers I read the following:

"It seems Richard is not willing to rewrite the program so that the
asymetric search is done normal.
it has IMO to do with the structure of genius. this static-exchange-evaluator in
combination with the asymmetry.
he would have to rewrite it completely from the scratch, and it seems he is not
sure if the rewrite would generate a stronger genius. IMO it would.
the asymmetry and the Static exchange evaluator was an instrument to beat 80-90
years opponents. but since nullmove came, it cannot win, it has not enough
advantages anymore."

What kind of asymmetry is meant? Is this asymmetry of static evaluation, or
search algorithm (pruning, move sorting, anything else) or both?

Is there any public information about Genius internals, maybe some threads on
this forum? I have read many times that Genius is *different* from other chess
programs, but what is the main difference?
